I build secure distributed systems, payment platforms, and cloud APIs at scale.
BrazilWhat I'm looking for
I've built secure distributed systems and customer-facing APIs at HostedScan, KRY, and FREENOW. At HostedScan, I expanded vulnerability detection to 300+ security risks, supported roughly 250 daily scans, and cut backend test execution time by about 5x.
I've led payment microservice design, healthcare integrations, and monolith-to-microservices migrations across European markets. I work across Java, Kotlin, Node.js, TypeScript, AWS, Terraform, and message queues, while mentoring engineers and raising standards for architecture, testing, and production operations.
